Hardware assessment.
Signed evidence.
Hardware assessment, entropy analysis, adversarial evaluation, and signed records support Accountable Evidence Plane. Each engagement selects the methods needed to answer a defined technical question.
01 / SIGNETMICROELECTRONICS ASSURANCE
SIGNET / PNT-1
Confidence begins
with the hardware.
SIGNET is SSX360’s signing and hardware-assurance platform. SIGNET PNT-1 extends that work into a positioning, navigation and timing field-unit design, with ML-DSA-87 signatures and Matrix Scroll protocol v2 integrity records.
Signed navigation records
The PNT-1 design binds navigation observations and integrity indicators into records intended for independent, offline review. Assessment considers the source data, signing context, and what each record can establish.
Design and evaluation
The PNT-1 field unit is in design development. Hardware testing and performance validation remain part of the development plan. Accountable Evidence Plane defines the methods and records needed for an agreed evaluation.
02 / EVIDENCE SOFTWARESSX360 / INTERNAL TOOLING
Signed evidence.
Controlled review.
Matrix Scroll and Scroll Console support SSX360’s internal evidence workflows. Together, they organize records by unit, check signed material, and prepare evidence for offline review. Each engagement defines the sources, handling requirements, and handoff.
SIGNING & VERIFICATION
Matrix Scroll
Matrix Scroll provides ML-DSA-87 signatures, SHA-384 record commitments, and explicit signer enrollment. It supports signed software and machine-action records, offline verification, and comparison with retained source records.
REVIEW WORKSPACE
Scroll Console
Scroll Console organizes imported inventory, document, test, and maintenance records by unit. It brings inspection, signer management, source comparison, and evidence exports into a private workspace.
Collect within scope
Group records around the unit and review question. Keep the collection context, assessment findings, and unresolved questions with the work.
Protect source content
Retain original source records under agreed access controls. Exported observations can carry cryptographic commitments in place of raw source values. Evidence handoffs can be encrypted for the intended recipient.
Compare the supplied record set
Compare a signed record set with retained originals to identify changed, missing, or reordered entries. A separately retained reference supports checks for rollback or conflicting history within the supplied evidence.
Review offline
Check signatures and the enrolled signer policy without a public service. Scroll Console compares Python and JavaScript cryptographic verification results; a missing result or disagreement cannot produce a passing review.
Private tools, scoped engagements
Development, repository access, and current distribution are private. Public Matrix Scroll onboarding, community contributions, releases, and support ended on October 8, 2026. Evidence deliverables are agreed through an SSX360 engagement.
Version 0.11.0 and earlier public distributions are historical and unsupported. Existing copies retain their original licenses, and local verification with an existing installation continues to work without matrixscroll.com.
03 / ENTROPYSUPPORTING METHOD
Entropy-source assessment
Entropy assessment examines a defined source and dataset within an agreed system context. The assessment records how the data was collected, the method used, observations, and the limits of the conclusion.
04 / ADVERSARIALSUPPORTING METHOD
Challenge the assumptions.
Adversarial verification examines assumptions and system behavior through authorized scenarios. The review records the scenario, observed behavior, findings, and unresolved questions. Wargame work uses the same agreed boundaries and review objectives.
